RabbitMQ 3.9.16

Core Server

Enhancements

Quorum queues: better forward compatibility with (currently in preview) RabbitMQ \ 
3.10.

Significantly faster exchange re-import from definitions
on subsequent node restarts. Initial definition import still takes
the same amount of time as before.

RabbitMQ nodes will now filter out certain log messages related to
connections, channels, and queue leader replicas receiving internal protocol messages
sent to this node before a restart. These messages usually raise more questions
and cause confusion than help.

It is still possible to detect relevant underlying events (node or connection \ 
failures)
from other log messages.

Bug Fixes

rabbitmq-upgrade await_online_synchronized_mirror is now a no-op in single node
clusters

Prometheus Plugin

Bug Fixes

One metric that was exposed via CLI tools and management plugin's HTTP API
was not exposed via Prometheus scraping API.
